  • Patent number: 9549534
    Abstract: A method for milking is provided in a milking system which includes a milking machine having a plurality of teat cups, which teat cups are attached to, and detached from, teats of animals as part of the milkings of the animals. The method determines whether an animal, which presents itself at the milking system, has a regular milking permission and when the animal has a regular milking permission the animal is milked in a regular milking procedure.

  • Publication number: 20150075434
    Abstract: A lip member of a teatcup liner for a teatcup includes a first end (3a) turned towards an udder of an animal to be milked; a second end (3b) turned away from the udder; a longitudinal center axis (x) extending through the first end and the second end; an annular base (60) extending around the longitudinal center axis; and a lip (61) with a lip edge (62) defining an opening for receiving a teat of the animal, the lip extending inwardly from the annular base towards the longitudinal center axis to the lip edge and having an oscillating shape with a plurality of oscillations seen radially from the longitudinal center axis, each oscillation including a peak portion (63) and valley portion (64), where the lip, at least in the rest state, slopes from the annular base towards the second end.

  • Patent number: 8356577
    Abstract: A combination of a teat cup and a flexible milk tube is shown. The flexible milk tube has a main duct and a plurality of secondary ducts for discharging milk from the teat cup and for applying vacuum in the teat cup. The main duct is confined by a duct wall extending around the main duct. The secondary ducts are included in the duct wall of the main duct. By including the plurality of secondary ducts in the duct wall of the main duct the flexible milk tube as a whole has a smaller cross-section than that of the known milk tube. The plurality of secondary ducts no longer need separate duct walls forming separate tubes either connected or not with the flexible milk tube comprising the main duct. This results in space saving.

  • Patent number: 7637228
    Abstract: A milk hose for connecting a milk collecting piece to a teat cup in an automatic milking plant comprises a first end area which is adapted to be fixed to the connection element of the teat cup and a second end area which is adapted to be fixed to the connection element of the milk collecting piece. Furthermore, said second end area has provided thereon an impact-absorbing area comprising elongate impact-absorbing elements, which, when subjected to a radial impact load, are deformed and/or bent at least sectionwise in a predefined preferred direction, and/or nipple-shaped impact-absorbing elements which are deformed and/or bent when subjected to said radial impact load. In addition, an impact-absorbing device for mounting on a milk hose is described.

  • Publication number: 20090283043
    Abstract: For a teat cup, a teat cup rubber liner (1) is proposed having a head part (2) having an inlet orifice (3) for a teat of an animal, this inlet orifice (3) being limited by an annular tube (4) and having a shaft part (5) connected to the head part (2), wherein, between the head part (2) and the shaft part (5), a region (6) is provided which makes possible relative motion between the head part (2) and the shaft part (5).

  • Publication number: 20040244699
    Abstract: The invention relates to a method for milking an animal, in particular a cow, according to which a characteristic (KG) of the milking operation is first determined. Said characteristic (KG) is composed of at least one of the following variables: the actual value (IW) of the milk flow (MF), the temporal modification of said flow and/or the accumulated quantity of milk (MM). A threshold value (SK) for determining the end of a milking operation is determined in accordance with the characteristic(s) (KG). The end of the milking operation is predicted using the characteristic (KG) and the threshold value (SK). An evaluation variable (BG) of the milking operation is determined during said milking operation, whereby this/these evaluation variable(s) (BG) take(s) into account at least one of the following variables: the actual value (IW) of the milk flow (MF), the temporal modification of said flow and/or the accumulated quantity of milk (MM).

  • Patent number: 6588364
    Abstract: The invention refers to a teatcup liner (3), a teatcup (1) having teatcup shell (2) and such a teatcup liner (3), and a milking member with at least two such teatcups (1). The teatcup liner (3) includes a head portion (3b), which is provided at a first end of the teatcup liner, and a pipe portion (3c), which extends from the head portion to a second end along a longitudinal axis (z) of the teatcup liner and which defines an inner space (5) arranged to receive a teat of an animal. The longitudinal axis forms a center axis of the inner space. The head portion includes an opening (9), which is intended to permit the introducing of said teat into the inner space (5). The head portion (3b) consists of a first part (10), which extends from a first side of a plane including the longitudinal axis (z), and a second part (11), which extends from the other side of said plane and which is larger than the first part.
